Mini Lesson
Numbers up to one million appear in populations, distances, and large data sets. Every number can be written three ways: standard form (digits only), word form (written-out words), and expanded form (each place value shown as an addition).
The Place-Value Chart to 1,000,000
- The seven place values from right to left: ones, tens, hundreds, thousands, ten-thousands, hundred-thousands, millions.
- Each place is 10 times greater than the place to its right.
- Use commas to separate every group of three digits: 345,206.
Standard Form
- Write the digits in order from greatest place to least.
- Insert a comma after every third digit from the right: 1,234,567.
- Example: three hundred forty-five thousand, two hundred six → 345,206.
Word Form
- Name the millions group, then the thousands group, then the hundreds group.
- Use a comma and the word "thousand" after the thousands group: "forty-five thousand, two hundred six."
- Zero in any place is not spoken: 345,206 has no tens, so tens are not named.
Expanded Form
- Break the number into the value of each non-zero digit and add them.
- 345,206 → 300,000 + 40,000 + 5,000 + 200 + 6.
- Skip any place whose digit is zero — do not write "+ 0".
Words to know
Place value
The value a digit has based on its position within a number
e.g. The 4 in 345,206 has a place value of 40,000.
Standard form
A number written using digits only with commas every three places
e.g. 345,206 is written in standard form.
Word form
A number written out using words instead of digits
e.g. The word form of 206 is two hundred six.
Expanded form
A number written as the sum of the values of each non-zero digit
e.g. Expanded form: 345 = 300 + 40 + 5.
Million
A number equal to 1,000,000 — one thousand thousands
e.g. A city of one million people is huge.
Tip: group digits in threes from the right, then insert commas. Read each group (millions, thousands, then the rest) separately.
